In my original post I should have mentioned that I've used the Reference 1s for over 5 years. An interview with Jack Oclee-Brown I saw on YouTube lead me to reduce the separation of the speakers to create an equilateral triangle and to remove toe-in. The sound improved considerably. The room is 14' X19' X 8' with books and posters.
In the living room I had LS50 W2s against the wall rationalizing that the pair of KC62 subs handled LF. But when I pulled them away from the wall the sound improved dramatically, with a nice sense of soundstage depth without compression.
